Sorry about the plug breaking off Bob, I'm sure you've gotten it out by now. As far as replacing the plug, I would suggest you check out replacing the plastic plug with an Anode Rod instead. It protects your water heater from corrosion by attracting the various corrosive elements in the water to the rod rather than the interior of your water heater. The Atwood rod is made out of magnesium and the Suburban Anode rod is made out of aluminum, so you need to know which heater your rig has. We've used them in our previous coaches and the seem to work as promised. I just installed a new one in my rig that has a drain valve in the plug for draining the tank as well.
Protect your water heater from corrosion. Anode Rods attract corrosive elements in water, so they attack the anode rod rather than the interior of your water heater's tank. Simply remove the plastic drain plug and insert the anode rod. Atwood Anode Rod is made of magnesium; Suburban Anode Rod is made of aluminum. When replacement is necessary, unscrew the old one and insert the new one. Anode Rods are easily replaced and should be checked every three months.
